Install redmine with MySQL in Ubuntu 11.04

Damaged hard disk, new hard disk, new re-installation of my software!

Based on my previous post (https://myotragusbalearicus.wordpress.com/2011/03/22/install-redmine-with-mysql-in-ubuntu-10-10/), I reinstalled redmine on Ubuntu 11.04. I also tried to follow http://www.x2on.de/2011/04/23/tutorial-redmine-with-git-and-gitosis-on-ubuntu-11-04/ without installing Git, but have had a lot of problems.

First, install the required packages (Ruby on Rails), apache modules, and then install redmine:

$ sudo apt-get install ruby rubygems subversion ruby-pkg-tools ruby1.8-dev build-essential apache2-prefork-dev libapache-dbi-perl libapache2-mod-perl2 libdigest-sha1-perl libcurl4-openssl-dev ruby  ruby1.9.1-dev libgemplugin-ruby libgemplugin-ruby1.8 libruby-extras libruby1.8-extras rake libmysqlclient15-dev
$ sudo apt-get install libapache2-mod-passenger
$ sudo apt-get install redmine redmine-mysql

If you like Gantt-charts:

$ sudo apt-get install librmagick-ruby1.8

Create the database for redmine:

$ mysql -u root -p
CREATE DATABASE redmine CHARACTER SET utf8;
CREATE USER 'redmine'@'localhost' IDENTIFIED BY 'redmine_password';
GRANT ALL privileges ON redmine.* TO 'redmine'@'localhost';

Configure the database settings:

$ cd /usr/share/redmine
$ sudo cp templates/database.yml.template config/database.yml
$ sudo vi config/database.yml

Sample config file using the default MySQL port (3306):

production:
  adapter: mysql
  database: redmine
  host: localhost
  username: redmine
  password: redmine_password
  encoding: utf8

Install Rubygem, because Ubuntu 11.04 has an older version:

$ cd /tmp
$ wget http://production.cf.rubygems.org/rubygems/rubygems-1.7.2.tgz
$ tar xvfz rubygems-1.7.2.tgz
$ cd rubygems-1.7.2
$ sudo mv /usr/bin/gem /usr/bin/gem-ubuntu
$ sudo ruby setup.rb
RubyGems 1.7.2 installed

=== 1.7.2 / 2011-04-05

* 1 Bug Fix:
  * Warn on loading bad spec array values (ntlm-http gem has nil in its cert
    chain)

------------------------------------------------------------------------------

RubyGems installed the following executables:
	/usr/bin/gem1.8
$ sudo ln -s /usr/bin/gem1.8 /usr/bin/gem

Now install Rails and rack

$ sudo gem install rails -v=2.3.11
$ sudo gem install rack -v=1.1.0
$ sudo gem install mysql
$ sudo gem install -v=0.4.2 i18n

Configure redmine:

$ cd /var/www
$ sudo ln -s /usr/share/redmine/public /var/www/redmine
$ sudo chown -R www-data:www-data redmine
$ sudo rake generate_session_store

If you get this error…

rake aborted!
no rakefile found

…just go to the redmine folder and run again… to get this new error:

$ cd /usr/share/redmine
$ sudo rake generate_session_store
NOTE: SourceIndex.new(hash) is deprecated; From /usr/share/redmine/config/../vendor/rails/railties/lib/rails/vendor_gem_source_index.rb:100:in `new'.
rake/rdoctask is deprecated.  Use rdoc/task instead (in RDoc 2.4.2+)
rake aborted!
uninitialized constant ActiveSupport::Dependencies::Mutex

As stated in Redmine forums http://www.redmine.org/boards/1/topics/22314, i added this line at the beggining of /usr/share/redmine/config/boot.rb:

require 'thread'

And now…

$ sudo rake generate_session_store
NOTE: SourceIndex.new(hash) is deprecated; From /usr/share/redmine/config/../vendor/rails/railties/lib/rails/vendor_gem_source_index.rb:100:in `new'.
rake/rdoctask is deprecated.  Use rdoc/task instead (in RDoc 2.4.2+)
WARNING: 'task :t, arg, :needs => [deps]' is deprecated.  Please use 'task :t, [args] => [deps]' instead.
    at /usr/share/redmine/lib/tasks/email.rake:170

But this is only a warning, so you can safeliy ignore it.

Let’s go with the next step:

$ sudo RAILS_ENV=production rake db:migrate
NOTE: SourceIndex.new(hash) is deprecated; From /usr/share/redmine/config/../vendor/rails/railties/lib/rails/vendor_gem_source_index.rb:100:in `new'.
rake/rdoctask is deprecated.  Use rdoc/task instead (in RDoc 2.4.2+)
WARNING: 'task :t, arg, :needs => [deps]' is deprecated.  Please use 'task :t, [args] => [deps]' instead.
    at /usr/share/redmine/lib/tasks/email.rake:170
<strong>rake aborted!</strong>
undefined local variable or method `version_requirements' for #<Rails::GemDependency:0x7f9ea62268b0>

Tasks: TOP => db:migrate => environment
(See full trace by running task with --trace)

That seems to be due to incompatible version of rubygems:

$ gem list

*** LOCAL GEMS ***

actionmailer (2.3.11)
actionpack (2.3.11)
activerecord (2.3.11)
activeresource (2.3.11)
activesupport (2.3.11)
i18n (0.4.2)
mysql (2.8.1)
rack (1.1.2, 1.1.0)
rails (2.3.11)
rake (0.9.2)

$ rails -v
Rails 2.3.11

$ ruby -v
ruby 1.8.7 (2010-08-16 patchlevel 302) [x86_64-linux]

Install rubygems update 1.4.2 (and uninstall any other rubygems version you already have):

$ sudo gem install rubygems-update -v='1.4.2'
$ sudo update_rubygems

To get another error…

$ sudo RAILS_ENV=production rake db:migrate
rake/rdoctask is deprecated.  Use rdoc/task instead (in RDoc 2.4.2+)
WARNING: 'task :t, arg, :needs => [deps]' is deprecated.  Please use 'task :t, [args] => [deps]' instead.
    at /usr/share/redmine/lib/tasks/email.rake:170
rake aborted!
No such file or directory - /etc/redmine/default/database.yml

This is more simple!

$ cd /etc/redmine/default
$ sudo ln -s /usr/share/redmine/config/database.yml

And now you finally can configure it:

$ cd /usr/share/redmine
$ sudo RAILS_ENV=production rake db:migrate
$ sudo RAILS_ENV=production rake redmine:load_default_data

And you can test redmine at

http://localhost/redmine

Wow, a little more complicated than in 10.10, at least for me!

As commented @ilian, if you have this error:

Please install RDoc 2.4.2+ to generate documentation.

Install it:

gem install rdoc -v=2.4.2
